Abstract
The utility model provides an upper guide plate adjustment device for a seamless steel-tube punch unit. A worm and gear 1 is arranged in a shell and is fixedly connected with a frame of the punch unit; a screw rod 5 is screwed in a worm wheel; two synchronous telescopic oil cylinders 4 are arranged at the two lower ends of a press plate 2; the middle part is fixed with a sliding framework 3; and the lower end of the screw rod is pressed in the groove in the middle of the upper surface of the press plate. When in use, the position of the lower end surface of the screw rod is adjusted according to the hole pattern, which is realized in a way that a motor drives the worm and gear. The upper guide plate and a lower guide plate are hoisted on a sliding carriage of the lower guide plate and then are pushed in the guide plate installation position; then the sliding device of the upper guide plate is fell until the sliding device is in contact with the guide plate and the automatic clamping of the guide plate is realized; the sliding framework of the upper guide plate is hoisted until the sliding framework is in full contact with a screw-down screw rod; therefore, the adjustment of the upper guide plate and the installation of the upper and the lower guide plates are finished.
Description
Technical field
The utility model belongs to the piercing mill of seamless steel tube technical field, especially a kind of upper guide plate adjusting device that is used for piercing mill of seamless steel tube.
Background technology
The upper guide plate adjusting device is one of vitals of seamless steel pipe two roller horizontal perforated machines, and upper guide plate and two rolls and bottom guide and top form closed type, and at high temperature solid bar is pierced into hollow seamless steel pipe through the punch pass.
Upper guide plate mainly bears huge draught pressure and frictional force, very easily wearing and tearing in perforation procedure.So according to the difference and the degree of wear of perforation pass, upper guide plate need carry out frequent replacing in process of production.As the pass adjustment with for upper guide plate provides enough critical components of big support force, the part that the upper guide plate adjusting device is responsible for depressing must be able to provide the enough big power of depressing, and upper guide plate is changed should be laborsaving and efficient.
Punch upper guide plate adjusting device was responsible for the pressure part complex structure in the past, and was highly higher, and it is longer usually to depress screw mandrel, and not only equipment investment and maintenance cost increase, and are unfavorable for that screw mandrel bears bigger pressure.In addition and since device space restriction make carriage up and down slidably scope dwindle, the adjusting range of pass is limited.
Summary of the invention
For solving above-mentioned existing problem, the utility model has designed a kind of upper guide plate adjusting device that is used for piercing mill of seamless steel tube, this device has adopted increasing oil cylinder stroke and the carriage amplitude of sliding up and down to realize, save manpower greatly, operating efficiency obviously improves.
For achieving the above object, the utility model adopts following technical scheme:
The described upper guide plate adjusting device that is used for piercing mill of seamless steel tube is made of worm and gear, pressing plate, balladeur train, oil cylinder, leading screw, wherein worm and gear is packed into, and housing is interior to be fixedly connected with the punch frame, screw in leading screw in the worm gear, two ends are provided with two synchronization telescope oil cylinders under the pressing plate, fixing closing with balladeur train in the middle of the pressing plate, the leading screw lower end withstands in the pressing plate upper surface intermediate groove.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, the utility model makes upper guide plate more change jobs to seem easy and convenient and quick, and the efficient of operation is greatly improved, and realizes automation mechanized operation easily.
2, the utility model is simple in structure, and manufacturing cost is lower, safeguards and convenience easy to maintenance.
3, the worm and gear shell directly bears roll-force, has effectively saved the device space, simplifies the structure, and also provides enough spaces for carriage slides up and down significantly.
4, oil cylinder stroke obviously strengthens, and the amplitude that carriage slides up and down significantly increases, and makes upper guide plate change more convenient, saving manpower.
Description of drawings
Fig. 1 is the utility model structural representation.
Among Fig. 1: the 1-worm and gear; The 2-pressing plate; The 3-balladeur train; The 4-oil cylinder; The 5-leading screw.
The specific embodiment
In conjunction with Fig. 1, the upper guide plate adjusting device that is used for piercing mill of seamless steel tube of the present utility model is made of worm and gear (1), pressing plate (2), balladeur train (3), oil cylinder (4), leading screw (5), wherein worm and gear (1) is packed into, and housing is interior to be fixedly connected with the punch frame, screw in leading screw (5) in the worm gear, pressing plate (2) is provided with two synchronization telescope oil cylinders (4) in two ends down, fixing closing with balladeur train (3) in the middle of the pressing plate (2), leading screw (5) lower end withstands in pressing plate (2) the upper surface middle part groove.
Worm and gear in the utility model has adopted the application specific architecture design, this part-structure is simplified, equipment investment and maintenance cost reduce, effectively reduce the outfit of equipment height, and the leading screw overall length is shortened, improved leading screw rigidity, for balladeur train significantly lifting created condition, the ability of bearing draught pressure significantly improves.
Aspect saving manpower, improving upper guide plate replacing efficient, the utility model has adopted increasing oil cylinder stroke and the balladeur train amplitude of sliding up and down to realize, so just can directly drop on the bottom guide upper guide plate, utilizing overhead traveling crane will go up bottom guide hangs together on the bottom guide slide, push the guide plate installation site then to, at this moment balladeur train just can slide into the lower surface down and touches upper guide plate and realize till the automatic card-loading.Removed from this way and need manpower or replace with the trouble that guide plate brings by means of specific purpose tool, manpower is saved greatly, and operating efficiency obviously improves.
During use, adjust residing position, leading screw lower surface according to the pass size, This move is realized by the driven by motor worm and gear.To go up bottom guide and hang together on bottom guide device slide and push the guide plate installation site, fall the upper guide plate carriage then up to contact and realize the upper guide plate automatic card-loading with guide plate.Rise the upper guide plate balladeur train up to fully contacting, just can finish the upper guide plate adjustment and reach the installation process that goes up bottom guide with depressing leading screw.
